WHEEL consrm'icrroiv.

T 0 all whom it may concern:

Be it known that I, HUGH W. SANFORD,

a citizen of the United States, and a resident of Knoxville, in the county of Knox and State of Tennessee, have invented a new and Improved lVheel Construction, of which the following is a full, clear, and exact description.

My invention is an improvement in wheel construction, and has for its object the pro-' vision of means for preventing wear on the hub and bearing sleeve of wheel mountings, wherein the wheel is journaled on the axle.

In the drawings :-Figure 1 is a longitudinal vertical section of the improvement,

is composed of the bearing proper encircling the axle, and a radially offset annular flange 4:, connected to the bearing by a web 5.

11 wheel 6 is provided with a hub 7, of greater internal diameter than the axle, and

. the hub is journaled on the axle, a roller bearing 8 being interposed between the hub and the axle. A roller cage 9 is provided and a collar encircles the axle, between an annular shoulder l 6on the axle, and the inner end of the bearing sleeve 2. The hub is provided with a bushing 10 between the rollers and the inner surface of the hub, and a plurality of washers 11, are arranged on the axle, be-

and the end of the. hub. T he said hub is closed at its outer end, andprovided with a threaded oil. opening 12, in which is threaded-a plug 13. The flange 4.- of the bearing extends outwardly over the inner end of the hub, and above and'below the axle a'transversebore 14' is provided, extending through the flange and the bearing. The central portion of'each"-bore is formed by registering of the flange, and in the outer surface of the hub, the latter groove being annular. A key 17', in the form of a bolt is passed through each bore, and is held in place in any suitable manner. bearing and hub in proper relative position, since each key is engaged with both parts, inside the bearing. The Washers 11 receive the thrust of the hub, and prevent undue Specification of Letters'ratent.

grooves in the inner'surface The keys hold the Patented July 2, 1912. Serial No. es4,7b0EISSUED wear of the web 5 of the hub. When the washers become worn, they may be replaced by others. The life of the bearing is thus greatly lengthened. It will be noticed that an oil chamber 19 is formed between the outer endof the axle and the closed end of the hub. An arc-shaped thrust block 20 is inserted'in the said chamber, and the ends of the block bear-against the inner face of the closed-end of the hub, while the central portion 'of the block bears against the ends of the axle. The inner end of the plug 13 extends between the ends of the block, and the block is held in-place by lugs 25, which are cast in the end of the hub. An opening 26 is provided in the thrust block for permitting the insertion of a tool in placing or removing the block.

The block receives the end thrust of the axle, and when worn may be removed and replaced by a new block. The principal defect in the construction in question, that is in loose wheels, is the wear from end thrust, in rounding curves. In the present construction, all'end thrust of the wheel pushing'inwardly, is received by the interchangeable blocks or washers at the center of the axle, thus reducing wear and friction to a minimum. 7 The. lugs in addition to their function of holding the thrust block in place, also acttotake' the end thrust, should the thrust washer 20 be omitted, or

lost from the wheel, at least until new thrust .washers can be inserted. The peculiar form of thrust block 20 places all of the end thrust of the wheel pushing-inwardly, on

the center of the axle. I claim 1. The combination naled, .a wheel having a hub journaled on the axle, a roller bearing between the huband the axle, a, washer at each end of the rollers, the bearing sleeve having a radially.

ofli'set annular flange overlying the inner end' of the hub, and having a web connecting theflange to the bearing sleeve, a plurality of interchangeablewashers encircling the axle'between the hub and .the web, the flange on the axle, the outer endof the hub being closed; and having an oil opening at the center, a filling plug 1n theop'ening, and an with the axle, of a bearing sleeve in which the axle is jour-.

' plurality of .dially oflset innergepd of the hub, and having a Web con- "thearc-shaped bearing bldck between the said hub and the adjacent end of the axle, the

body of the block engaging the axle end,

and the ends thereof engaging the hub on each side of the inner end of the plug.

The combination with the .axle', of a bearing sleeve in which the axle is journaled, a-wheel having a hub the axle, the bearing'sleeve having a raannular flange overlying the fleeting theflange to the bearing sleeve, a
